IPC: G01S7/02
Filed: 1980-02-27
Abstract: PURPOSE:To detect an accurate angle error signal while receiving any polarized wave with efficiency, by controlling the phase difference plate of an angle error circuit and that of a reference signal circuit at a proper rotation ratio. CONSTITUTION:The 90 deg. phase difference plate 34 of an angle error signal circuit and 180 deg. phase difference plate 5 of a reference signal circuit are controlled at rotation ratio 1:2, and 180 deg. phase difference plate 35 of the angle error circuit and 180 deg. phase difference plate 5 of the reference signal circuit are also controlled at rotation ratio 1:1. The output of 180 deg. phase difference plate 35 is branched into polarized wave components crossing each other at right angle; one component is phase-detected by phase detector 37 with the output of voltage-controlled oscillator 9 synchronizing with a reference signal to obtain the 1st angle error output, and the other branched component is phase-detected, being 90 deg. out of phase with the 1st angle error output, by phase detector 47 by using the output of voltage-controlled oscillator 9 to obtain the 2nd angle error output which crosses the 1st angle error output at right angle.

Abstract: PURPOSE:To make the holograms from which color reproduced images are obtainable by letting plural sets of color information be carried in the object light carrying object information and passing the same through apertures in the method of making holograms by incidence of said object light and reference light to a hologram recording medium. CONSTITUTION:A stereoscopic picture element 101 is lighted simultaneously by three coherent lights R, G, B of different wavelengths through a diffusion plate 11.

IPC: G03G21/14
Filed: 1994-02-23
Abstract: PURPOSE:To improve the S/N of a detecting means, and reduce its erroneous detection by using a transparent transfer sheet carrying belt and a reflecting member to increase the light quantity returned to an optical sensor when no resist mark is present on the transfer sheet carrying belt. CONSTITUTION:To read each resist mark, a lens 15 and a light emitting and receiving part 17 for emitting an infrared ray to be absorbed by each resist mark are provided. In the place where no resist mark is recorded, the light emitted from the light emitting and receiving part 17 is transmitted by a transfer sheet carrying belt 1, reflected by a reflecting member 18, again transmitted by the transfer sheet carrying belt 1, and detected by the light emitting and receiving part 17, while, in the place where the resist mark is recorded, the light emitted from the light emitting and receiving part 17 is absorbed by the resist mark.

Title: Photodetector
Inventor: HATA SUSUMU
IPC: H01L31/10
Filed: 1985-02-14
Abstract: PURPOSE:To enable to apply electric field with a uniform strength to the P-N junction, by utilizing semiconductor materials in which a band gap energy of a first semiconductor layer is larger than that of a second semiconductor layer, and by inputting light to be detected in the direction transverse to every semiconductor layer. CONSTITUTION:Reverse bias voltage is applied across ohmic electrodes 25, 26. Since a two-dimensional electron gas layer is formed between an N-type InAlAs layer 22 and N-type InGaAs layer 23, the potential of the ohmic electrode 25 is applied to a P-N junction being formed between a P-type InGaAs layer 24 and depletion layer 27 without almost varying the value. Accordingly, extension of the depletion layer 27 is uniformed over the entire P-N junction so that sensitivity to incident light 28 can be approximately uniformed over the entire light receiving area. That is, positive holes excited by the incident light 28 drift toward the semiconductor layer 24 and are detected from the ohmic electrode 26 in an extremely short time as a signal. Thus electric field strength in the photo sensitive layer can be approximately uniformed so that sensitivity distribution in the light receiving plane can be uniformed.
